There have been some quite significant changes in the way Moodle looks, as we've seen so far in this book. We'll begin with Themes:
The themes structure has been completely rewritten for Moodle 2.0.Themes that worked in 1.9 needed to be updated to work in 2.0. There is a wide variety of attractive new themes available. If you need to update your own theme or would like information on Moodle 2.0 theming, you will find the documentation at http://docs.moodle.org/en/Development:Themes_2.0 helpful
New to Moodle 2.0 are the following:
Designer Mode: Turn this on so you're not served cached versions of themes, if you are designing themes or developing code.
Allow theme changes in the URL: Enabling this will let users alter their theme via their Moodle URL using the syntax
Allow blocks to use the dock: Enabling this will allow users to dock blocks if the theme supports it.
